Invisible zipper

user-7376969 | Posted in Techniques on

Recently when putting in an invisible zipper, the neckline became distorted after finishing neckline facing.  I’d love to know how to finish the top of the zipper so I wouldn’t have this problem. The rest of zipper looks great. The fabric is ponte knit.

    Helpful enough! Thanks for sharing this article! I need this too as I often find my invisible zipper is glaring with flaws. Indeed, it requires technique and skills.

    Hi, I've had good luck when I make my lining a smidgen smaller than my fashion fabric. It pulls the seam a bit to the inside.

    My problem ,as picture indicates was that the neckline got distorted or stretched when I sewed the facing at the top of zipper. That is where I need advice. How much space should be above the zipper tape when putting in an invisible zipper.

    I apply the zipper leaving about a 3/4" space from the zipper stop to the top end of the garment, ( you can also allow the zipper to slightly overlap the neck edge). It is at this time I apply the facing. After installing the facing, I follow the usual steps when attaching a neck facing i.e., I clip,.. trim and understitch the seam to the facing. The final result is a smooth and clean neckline where the zipper stops. If I apply the facing first and the zipper after, the top edge of the neckline (where the zipper ends) becomes distorted and, instead of having a smooth neckline, it tends to have a big bump at the zipper opening. I often had this problem but I finally figured out what I was doing wrong. I hope this helps.
